> Huls hadn’t heard of Schnitzler syndrome, either. He came upon it by using the database PubMed to look for a disease that matched the patient’s symptoms. He made a list of her symptoms and abnormalities. To get the full picture, he combed through her earlier electronic medical records, now archived in an old electronic warehouse, and found that her symptoms had started maybe a decade earlier. Then he looked for a disease that fit. It took hours before articles on this strange disorder began to appear. As he read, he suspected that she had it.

Is this database open? If so, anyone in the same situation as the daughter in this article could spend the hours, rather than hoping a professional will. Not to self-diagnose, but to narrow down the list to a number of candidates the professionals are willing to look through. Sure, what takes the M.D. 6 hours might take me 40 hours, but if the alternative is 10 years of suffering for someone I love, it's easily worth doing.

On a similar note, I have combed through a bunch of research on a particular type of medication recently, and I hope the fruits of my labour will pay off. Time will tell. Either way, I have learned a lot.

Once you are dealing with somethibg that is difficult to diagnose and/or resistant to treatment (I might argue the two are the same thing on a fundamental level), a surprisingly large portion of medical care turns DIY. They never tell you this but unless you are actually made of bucks and can visit the best specialists in the world, it won't take long until you know more than the doctors you meet about the specific problem you're dealing with.

Pubmed itself is open (just google "pubmed"). However, while many scientific publications are open access, many more are not.

I find that google scholar does a pretty good job at searching. I typically start with google before using pubmed.

Then you need a place to store your papers. I like to use F1000 workspace.

If your doctor is not helping you, get a new one, preferably in a big city with a university-affiliated hospital. These MD deal with highly educated levels of patients and colleagues, and they like it.

True, but

sad that it needs to exist, but good that it does.

It does, plus it has the great advantage that it will find a PDF of the paper posted by the author (or someone else) on a webfolder somewhere. Pubmed only links to the "official" paper publication, plus some open repositories in some cases.

I've done this with various doctors, trying to figure out what the hell is wrong with me. In my experience, as soon as you start telling them they just think you're a crazy hypochondriac who sends too much time on the internet.

I think a lot of it depends on how you present it and who you see. I have had the best results when leading the doctor on just to the point of tricking them into thinking they came up with the idea themselves. Play to their vanity!

I'm guessing they're just pattern matching as most of the time, they'd probably be correct.

Yep, that makes sense... problem is when something doesn't match the patterns, they just shrug and give up.

My first reaction to these things is that there should be a large database of diseases and symptoms along with some statistics about how strong the correlation is between the disease and symptoms. I don't mean "database" like pubmed. I mean something more machine readable with consistent coding so a symptom might be "elevated IgM" in english. The trick is coding something like that with consistent names for the tested item and consistent definitions of "elevated". Perhaps the definition of elevated would depend on the disease?

One should be able to then filter the disease database based on symptoms. Doctors seem to do this in their head, but they are not comprehensive stores of information. I suppose the problem is in the encoding of symptoms, it's not that simple.

Re:Her Various Symptoms Seemed Unrelated, Then One Doctor Pu... by jdmichal on Sunday February 18, 2018 @10:13AM (#16406392)
The only appropriate definition of elevated is higher than normal for that patient. Unfortunately, doctors rarely have a baseline to work from, so they use statistics instead. A relative of mine had a PSA test that read statistically normal. Luckily he looked at the actual number and saw that, while it was within statistical normal, it was in fact higher than any other prior reading for him. Further testing came up positive for prostate cancer. If he hasn't been paying attention, that would have been another year of cancer until the next check.

It’s hard to convince institutions to release data locked up in EHRs (eg EPIC) due to the labor involved (EPIC is not well structured for this), risk of accidentally leaking PHI, and general motivation (getting hold of useful data is the bread and butter for career researchers).

The main problem here is human body works in mysterious ways.

We are by definition reacting different, and unfortunately statistics are not helping on this case.

Basically, we have:

- too many illnesses (I guess 10% of top common health problems, covering 90% of all problems)

- for each illness, we have N number of symptoms (which unfortunately all or only a subset of this can occur)

- then we have fake symptoms (statistically out of threshold values but we are living fine with them)

this is generating a big number of combinations.

With this much combinations, it is requiring extensive amount of tests.

As everything health is also optimized for the greater good. Which requires optimum cost management.

So basically medicine today, with statistical approach, is happy to skip 1%, if it can fix 99% with 90% less cost.

I think this is probably the easy thing to fix when it comes to searching, as you could pretty much leave out the common diagnoses as they'd likely have been tried - Imma call this the "Dr House, is it Lupus?" filter.

From there, you could have "try this" filter, and see what the results are. I wonder what the overlap is between tests and symptoms, but surely with 10 tests and 10 symptoms, most illnesses could be mostly identified?
